At the New Year London Open tournament there is a Pair Go tournament during one of the evenings.
14 pairs took part. Winners were Boris Mitrovic & Fynn Bachmann. Second were Chris Volk and Andre Stadtler; third were Jonathan Green and Andrew Russell.
The British Pair Go Championship is open to male and female pairs who play together at the same board without conferring.
The web has many sites giving the rules of Go.
